Definitions
- the present invention relates to a roller blind device for a vehicle window and a cable pulling device for such a roller blind device.
- roller blind devices are each configured with a roller blind hanger, which is adjustable or movable between a covering position and a release position.
- the Rollobehang is usually wound on a roller shaft when it is in the release position. To move the Rollobehang in the covering position, this is unwound from the roller blind shaft and clamped along the vehicle window.
- traction means and other pressure means are known.
- traction means are also known, which in particular in the form of cable systems subtract a tension rod of the roller blind suspension or pull it upwards and thus ensure unwinding of the roller blind suspension from the roller shaft.
- a disadvantage of the known solutions is that a balance must be created for the changing winding diameter of the roller blind shaft. Due to the fact that the Rollobehang on the roller shaft and thus also on itself or is handled by itself, the winding diameter of the roller shaft changes along with the remaining, still wound Rollobehang with each revolution. In other words, a different length is released to Rollobehang depending on the current winding situation per revolution of the roller blind. While at the beginning, so with the Rollobehang in release position still a maximum length is handled Rol Rol Hang per turn, just before reaching the covering position by the unwound position of the Rollobehangs per revolution of the roller shaft a much lesser Unwind the length of the roller blind per revolution.
- a roller blind device for a vehicle window is formed.
- the roller blind device on a Rollobehang for covering the vehicle window in a covering position.
- the Rollobehang is equipped with a pull rod for unwinding the Rollo hang from the roller blind shaft.
- the roller blind shaft adjacent to the take-up on both sides in each case a cable pulling device, each with a rope. This rope is connected at one end to the tension rod and at the other end with a pulley for winding the rope to unwind the Rollobehangs of Rollowelle.
- Each cable pulling device further comprises a deflection device for deflecting the rope above the tension rod.
- the pulleys of the cable guide each have a cable guide for a side by side guided winding the rope with tapered Aufwickel malmesser.
- a roller blind device according to the invention is basically based on the technical implementation of known roller blind devices with a roller blind hanger with tension rod on the one hand and a Aufwickelitzkeit this Rollobehangs on the roller blind shaft.
- the cable pulling device is provided in order to enable the removal of the Rollobehangs from the release position in the covering position. It is therefore a train system which applies a force on the pull rod via a cable in order to remove it from the release position and thus from the roller shaft.
- the rope runs from the tension rod up to the deflection devices described and in lateral guide elements preferably back down to the respective pulley.
- the pulleys are connected to the rope so that when unwinding the Rollobehangs of the roller shaft with the same direction of rotation, the pulleys provide a winding of the rope attached thereto.
- the rope is therefore wound over the pulleys and this winding direction and thus the shortening of the rope length passed on the deflecting device to the tension rod of the Rollobehangs. This will now be deducted in this way in a tense situation and moved to the covering position.
- the pulleys are now provided with a cable guide, which results in that the rope is not on top of each other or on itself, but rather side by side in a guided manner up and unwound.
- These cable guides can be configured, for example, in the form of the later explained guide walls. This ensures that with each revolution and at each relative position of the Rollobehangs relative to the roller shaft an exact positioning of the rope on the respective pulley is assigned by the respective cable guide. This also ensures that the tapered Aufwickel malmesser on the pulley is also specific to the respective relative position of the Rollobehangs to Rollowelle.
- the tapered embodiment of the take-up diameter of the pulleys leads to the fact that a resilient compensation of the change in the unwinding diameter at the roller shaft is no longer or only to a smaller extent necessary.
- the compensation of the tapered unwind diameter is compensated by the geometric correlation with the tapered Aufwickel malmesser the pulleys so to speak in a geometric manner.
- the deflection of the rope is preferably provided in the deflection devices fixed above the tension rod, for example in corresponding lateral guide portions of the cable pulling devices. Also, you will find more details later.
- the pulleys are connected rotationally fixed to the roller shaft or connected so that they are moved in the same direction with the same rotational speed together with the roller shaft. It is of course irrelevant whether it is the drive of the roller blind shaft and thus also the pulleys to a manual drive or an automatable by a motor drive.
- At least the cable pulley of one of the two cable pulling devices has a continuously changing take-up diameter, in particular an archimedically shaped take-up diameter.
- a continuous change can lead in particular to a gentle and low-wear winding the ropes on the pulley.
- the pulleys of all cable pulling devices are identical or substantially identical.
- roller shaft is displaceable along the winding axis.
- a roller blind shaft can also be referred to as a traveling wave.
- Vehicle windows are often arranged laterally or inclined in the direction of travel shifted or provided with a corresponding parallelogram-like geometry.
- a roller blind hangup is wound obliquely or adapted to the angle of inclination of such parallelograms on the roller blind shaft. When unwinding, this would lead to a compensation of this non-parallel unwinding for parallel arrangement of the roller shaft is possible or necessary.
- the storage is preferably carried out at the ends behind the respective cable pulling device or behind the respective pulley.
- the cable guide a pulley a cable pulling device in particular all cable guides all pulleys, have a guide wall, which is arranged in the form of a spiral around the Aufwickel malmesser the pulley and fixed with a relative to the roller shaft Guide projection meshes for a shift of the roller shaft along the winding axis.
- This can be provided by the cable guide an additional functionality.
- the sliding bearing of the roller shaft is provided in this way with a positive guidance through this guide wall.
- the cable guide pulley receives in this way an additional function, namely the active and defined displacement of the roller shaft along the winding axis.
- the Distance between the individual guide walls preferably corresponds to the rope thickness plus an additional clearance of about 5% to about 10% of the rope thickness.
- the spiral-like arrangement of the guide wall is preferably designed uniform.
- At least the deflection device of a cable pull device in particular all deflection devices, have an adjustment section for setting the relative position to the roller shaft.
- the deflecting devices are in particular transversely and / or along to the cable pulling direction or to the unwinding of the Rollobehangs ausgestaltbar.
- An adjustment transverse to the cable direction leads to an adaptation to the corresponding window width.
- An adjustability in height means that an adjustment or fine adjustment to a length of the rope or the maximum covering position of the Rollobehangs is possible.
- a particularly simple embodiment of such an adjustment section is the embodiment by the combination of a slot with a screw connection.
- a roller blind device in a roller blind device according to the invention, at least one pull-wire device, in particular both pull-wire devices, have a spring-elastic compensating means for the cable.
- This resilient compensating means may be arranged within the force path of the rope as well as adjacent to this force path, and exert the corresponding resilient compensating force laterally on the rope.
- it is possible in this way to pull out a so-called lots from the rope and to avoid in this way unwanted drape in the Rollobehang.
- a compensation for temperature fluctuations or over the duration of the entire use of the roller blind device a reduction in wear can be provided in this way.
- the cable is attached at all connection points with the same or substantially the same type of connection to avoid the complexity of the connection.
- the corresponding counterpart component that is to say the tension rod and / or the cable pulley, is preferably designed with a corresponding form-fit section and / or a corresponding frictional engagement section and / or a corresponding frictional connection section in order to be able to receive the corresponding attachment as a function of the selected attachment.
- the deflection device is formed integrally with a guide device next to the roller blind curtain.
- a guide device next to the roller blind curtain This is to be understood in particular as a monolithic or integrally formed design.
- the deflection device can be molded directly in the one-component method and / or in the two-component method.
- the guide device corresponds to a lateral cable pull rod and protects the rope running therein of the respective cable pulling device.
- a cover flap for covering the roller blind hanger in the release position is arranged above the roller blind shaft, with a pretensioning device for pretensioning the cover flap in the opening direction.
- This cover covers the exit slot of the roller blind, through which the pull rod and then the roller blind hang can be pulled from the release position into the covering position.
- the cover flap is equipped with a biasing direction in the opening direction. This results in that the cover flap is pulled with a corresponding projection on the pull rod against this biasing force of the biasing device in the closed position. The overall functionality is facilitated in this way and at the same time the Rattling probability of such a cover flap reduced. Last but not least, at two or more points a corresponding projection on the pull rod can pull the cover flap in order in this way to be able to effectively avoid unwanted twisting of the cover flap.
- Another object of the present invention is a cable pulling device for a roller blind device according to the invention.
- a cable device each has a cable which is connectable at one end to the tension rod and connected at the other end with a pulley for winding the rope for unwinding the Rollobehangs of the roller blind shaft.
- the pulley on a cable guide for a juxtaposed guided winding the rope with tapered Aufwickel malmesser.
- the individual components of the cable pulling device are preferably designed such as have been explained in detail with respect to the roller blind device according to the invention.
- the cable pulling device can be used both on one side and on both sides in a corresponding roller blind device.
